CodePen on MDN

January 24, 2016

Heads up! This blog post hasn't been updated in over 2 years. CodePen is an ever changing place, so if this post references features, you're probably better off checking the docs. Get in touch with support if you have further questions.

It's pretty cool seeing demos on MDN1 have an "Open in CodePen" button. As in "Mozilla Developer Network", the massive and most comprehensive documentation for web technology out there. ❤
